The cause for their split remains unknown, but several sources have reported that Cannon cheated on Carey on more than one occasion.

Insiders claim that Cannon filed papers on December 12. The exact terms of the divorce are not known, but it is believed that Nick and Mariah are ending their marriage amicably and sharing custody of their twins, Morrocan and Monroe.

The timing of Cannon's filing is interesting for a number of reasons.

Just days before the legal wheels began to turn, Mariah was three hours late for a taping of the NBC Rockefeller Center Christmas tree lighting.

Sources stated that Mariah blew off the taping because she was deeply involved in discussions with her lawyers regarding her divorce.
